    Den statskloka resan: Adelns peregrinationer 1610–16802018Doctoral thesis, monograph (Other academic)
    Abstract [en]

    This thesis deals with foreign travel undertaken by the Swedish nobility during the 17th century. The first part contains a close examination of Swedish university orationes on the importance of foreign travel. The focal point of these speeches is prudentia, ‘prudence’, ‘practical judgement’, ‘discretion’, which is considered to be indispensably necessary for statesmen, and preferably acquired by traveling abroad.

    The second part of the thesis deals with traveling in practice. Journals, letters and accounts are scrutinized in order to map where the travellers went, and how much time and money they spent in various places and on different activities. The results show that the more or less compulsory studies at Dutch and German universities were combined with exercitia, i. e. physical exercises, most prominently dancing, fencing and riding. From the 1620s France became more important, and also, from the 1640s, Italy. As their British, Danish, Dutch and German peers, the Swedish noblemen after their sojourn in Paris visited the Loire valley and also made Il giro d’Italia. The growing importance of Paris became evident from the middle of the century: Although it proved extremely expensive, the noblemen spent as much time as possible in the French capital, which was by now compendium orbis, the place where everything desirable in the world was to be found, where exercitia of the best kind flourished and where exquisite manners could be acquired.

    The third part of the thesis studies how the travellers acted when they arrived at home. A study relating to the 1660s demonstrates that a returning grand tourist had to spend a considerable amount of money on conspicuous consumption to reinstate himself in the society and position himself as a liable state servant and marriage partner.

    A general result of the thesis is that traveling undertaken by the nobility formed a part of the 17th century state building process and that it was used as a means of competition both within the nobility and between the nobility and the rapidly growing class of bourgeois civil servants.

    Grön infrastruktur i urbana miljöer2018Book (Other academic)
    Abstract [sv]

    Grön infrastruktur i urbana miljöer är en högaktuell fråga i de nordiska länderna eftersom den höga urbaniseringstakten innebär att allt mer naturmark tas i anspråk för byggnationer och infrastruktur i form av till exempel vägar. Vid planering av ny bebyggelse behöver möjligheterna att återskapa natur och öka biologisk mångfald beaktas. Eftersom människors hälsa främjas av vistelse i naturen samt att en stor andel av befolkningen föredrar att bo naturnära finns här en win-win situation att ta till vara. I denna rapport ger vi exempel på fyra olika koncept som kan användas vid stadsplanering för att gynna och stärka grön infrastruktur. Vi ger också en rad konkreta exempel på lyckade projekt i urbana miljöer och gör en analys av hur de har stärkt ekosystemtjänster och därmed grön infrastruktur.

    Påverkansbedömning för ytvatten enligt EG´s Ramdirektiv för vatten - tillgängliga metoder, verktyg och modeller samt utvecklingsmöjligheter för SMED&SLU2004Report (Other academic)
    Abstract [sv]

    Enligt EG´s Ramdirektiv för vatten – i rapporten benämnt Vattendirektivet – ska en första

    analys av påverkan och dess effekter på vattenstatus ske under 2004 och rapporteras till

    EU-kommissionen i mars 2005. I bedömningen som utförs 2004–2005 ska även en

    prognos för perioden fram till 2015 ingå. I föreliggande rapport redovisas metoder, verktyg

    och modeller för att klara databehovet för denna analys. Rapporten redovisar också i vad

    mån SMED&SLU och erfarenheter från TRK-projektet kan bidra med data till påverkansbedömningen

    samt utvecklingsmöjligheter för att ytterligare anpassa systemutvecklingen i

    SMED&SLU till Vattendirektivets krav på data.

    Rapporten fokuserar på föroreningspåverkan och dess effekter i form av övergödning samt

    fysisk påverkan i form av flödes- och nivåreglering. Även andra typer av föroreningspåverkan

    (försurning, metaller, organiska miljögifter och bekämpningsmedel), fysisk

    påverkan (nivåsänkning, vattenuttag, vandringshinder/dammar och strukturell förändring)

    och övrig mänsklig påverkan redovisas.

    För att underlätta de analyser som ska göras är det en stor fördel om påverkansdata kan

    kopplas till enskilda vattenförekomster och därmed också vara möjliga att ha med i

    kartpresentationer. För att klara att hantera såväl data som beskriver ytvattenförekomsternas

    läge och gränser, som data som beskriver status och påverkan på dessa ytvattenförekomster,

    behövs en gemensam databastruktur. Varje ytvattenförekomst kopplas här till

    successivt större avrinningsområden i ett hierarkiskt system. Den minsta enheten är

    ytvattenförekomstens avrinningsområde följt av SMHI:s delavrinningsområden, TRKområden,

    huvudavrinningsområden och slutligen vattendistrikt. Förslag ges på kartunderlag

    som följer denna databasstruktur för en första identifiering av betydande

    påverkan inom avrinningsområden i Sverige.

    För olika typ av metoder, verktyg och modeller som kan användas för kvantifiering av

    påverkan och dess effekter redovisas bedömningar av möjligheterna till tillämpningar i den

    påverkansbedömning som ska göras under 2004–2005. Dessutom ges en mer ingående

    beskrivning av ett urval av modeller. Urvalet är baserat på att modellen är, a) anpassad för

    svenska förhållanden, b) tillämpad på svenska vattensystem, c) allmänt tillgänglig

    (antingen att använda eller att erhålla data från) och d) dokumenterad.

    För varje modell redovisas bl.a. syfte, typ av påverkan som kvantifieras, koppling till

    faktorer för tillstånd och effekter, tidsupplösning och geografisk upplösning, styrka och

    svaghet samt plattform och programvaror. Med hjälp av denna information ska man kunna

    avgöra vilken modell som är relevant för olika situationer. Dessutom ges information om

    internetlänkar, modellhistorik, ingående submodeller, relevanta referenser och kontaktuppgifter

    för att få tillgång till data eller resultat från modellen i fråga.

    För det inledande arbetet med karaktärisering och påverkansbedömning inför rapporteringen

    2004–2005 kan man prioritera att beskriva påverkan av eutrofierande ämnen. Man

    börjar då med att inom ett huvudavrinningsområde först lokaliserar de största punktutsläppen

    av fosfor och kväve. Befintliga TRK-data avseende beräknad kväve- och fosforbelastning

    per TRK-område för perioden 1985–2000 samt underlagsdata kan primärt

    användas. Först måste dock en uppdelning av TRK-områdena på de fem Vattendistrikten

    samt sammanlänkning av TRK-områdena med SMHI:s kustområdesregister göras.

    5

    För många större sjöar och många kustvatten kan sannolikt eutrofieringsstatus klassas med

    hjälp av information från nationell och regional miljöövervakning och samordnad

    recipientkontroll. Om det inte finns data från recipientkontroll i en vattenförekomst så är

    det inte sannolikt att vattnet är betydligt påverkat av punktutsläpp. TRK-systemet och

    resultat från TRK-beräkningar kan användas för att identifiera större områden som är

    eutrofierade p.g.a. läckage från jordbruksmark.

    Om behov finns skulle förnyade beräkningar kunna göras för avrinningsområden som är

    mindre än TRK-områdena t.ex. på delavrinningsområdesnivå. En möjlighet är också att

    beräkningar på delavrinningsområdesnivå endast görs för de TRK-områden som identifieras

    ha betydande påverkan från kväve- och fosforbelastning. Ett tröskelvärde för vad

    som är betydande påverkan måste i så fall tas fram t.ex. baserat på avvikelse från den

    ”naturliga” bakgrundsbelastningen. Ytvattenförekomster i TRK-områden med liten

    närsaltpåverkan, d.v.s. under tröskelvärdet, skulle då kunna grupperas och klassas som god

    status eller bättre m.a.p. kväve och fosfor och ytvattenförekomster med betydande

    närsaltpåverkan (över tröskelvärdet) skulle kunna klassas som ”riskvatten” med måttlig

    status eller sämre.

    Sammanfattningsvis kan således SMED&SLU tillhandahålla data som rör kväve- och

    fosforbelastning på vatten från punktkällor och diffusa källor. Exempel på data som kan

    tillhandahållas är bruttobelastning, nettobelastning och källfördelad belastning av kväve,

    bruttobelastning av fosfor, normaliserad markanvändning och avrinning. En viss

    anpassning kan emellertid krävas för att uppfylla vattendirektivets krav. Exempelvis bör

    upplösningen generellt förbättras till delavrinningsområdesnivå (i varje fall inom TRKområden

    som identifieras ha betydande närsaltpåverkan). Nya kunskaper om fosfor bör

    också implementeras för att kunna göra korrekta beräkningar av både brutto- och

    nettobelastning. Det beräkningssystem som beräknar diffusa utsläpp kan på sikt också

    utvecklas till att hantera andra ämnen, exempelvis metaller.

    Ett utökat samarbete inom SMED&SLU kan, om efterfrågan och tillgång på data finns,

    resultera i att SMED&SLU också kan komma att tillhandahålla påverkansdata rörande

    markanvändning, reglering och vattenuttag.

    Topological and Scaling Analysis of Geospatial Big Data2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Geographic information science and systems face challenges related to understanding the instinctive heterogeneity of geographic space, since conventional geospatial analysis is mainly founded on Euclidean geometry and Gaussian statistics. This thesis adopts a new paradigm, based on fractal geometry and Paretian statistics for geospatial analysis. The thesis relies on the third definition of fractal geometry: A set or pattern is fractal if the scaling of far more small things than large ones recurs multiple times. Therefore, the terms fractal and scaling are used interchangeably in this thesis. The new definition of fractal is well-described by Paretian statistics, which is mathematically defined as heavy-tailed distributions. The topology of geographic features is the key prerequisite that enables us to see the fractal or scaling structure of the geographic space. In this thesis, topology refers to the relationship among meaningful geographic features (such as natural streets and natural cities).

    The thesis conducts topological and scaling analyses of geographic space and its involved human activities in the context of geospatial big data. The thesis utilizes the massive, volunteered, geographic information coming from LBSM platforms, which are the global OpenStreetMap database and countrywide, geo-referenced tweets and check-in locations. The thesis develops geospatial big-data processing and modeling techniques, and employs complexity science methods, including heavy-tailed distribution detection and head/tail breaks, along with some complex network analysis. Head/tail breaks and the induced ht-index are a powerful tool for geospatial big-data analytics and visualization. The derived scaling hierarchies, power-law metrics, and network measures provide quantitative insights into the heterogeneity of geographic space and help us understand how it shapes human activities at city, country, and world scales.

    Slutrapport: Att mediera information om vårdmöjligheter för nyanlända: Evaluering av SLL:s kommunikation 2015/162018Report (Other academic)
    Abstract [sv]

    Under hösten 2015 och våren 2016 anlände många människor på flykt till Sverige. Runt omkring i landet uppstod då ett behov av att informera dem som kommit om deras förutsättningar, inte minst när det gällde hälso- och sjukvård. Stockholms läns landstings (SLL) reaktion på denna kommunikationsutmaning var bland annat att producera broschyrer och affischer med information för asylsökande.

    I vårt samarbetsprojekt har vi utvärderat informationssatsningen, och vi har sökt materialets informationsvägar, från landstinget till potentiella vårdtagare, via organisationerna och vårdinstitutionerna. Forskningsfrågorna är:

    -          Hur ges informationen, av vilka, till vilka och var?

    -          Vilka möjligheter och hinder har siktats?

    Vår studie är språkvetenskaplig och fokuserar samspel, samtal och kontexter där aktörer använder och tolkar vårdinformation.

    Något som vi ser som ett viktigt resultat från vår studie är att vi kan bidra till att synliggöra ett övergripande dilemma i samhället. Det finns en stor beredskap och en stark vilja att hjälpa och välkomna personer som är nya i Stockholm och Sverige. Det finns också god kunskap om hur man kan göra det. Samtidigt är viljan att upprätthålla och befästa gällande regelverk och system stark. Vi har sett hur dessa riktningar ofta hamnar på kollisonskurs med varandra och hur det verkligen försvårar både för den som vill hjälpa och den som behöver hjälp. SLL, och andra myndigheter och verksamheter, befinner sig tillsammans med den enskilde mitt i detta problem. I utformningen av framtida informationssatsningar kan man ha som mål att minska dilemmats konsekvenser i så stor utsträckning som det är möjligt.

    Modeling, Analysis, and Interpretation of Photoelectron Energy Spectra at Enceladus Observed by Cassini2018In: Journal of Geophysical Research - Space Physics, ISSN 2169-9380, E-ISSN 2169-9402, Vol. 123, no 1, p. 287-296Article in journal (Refereed)
    Abstract [en]

    The Electron Spectrometer (ELS) of the Cassini Plasma Spectrometer has observed photoelectrons produced in the plume of Enceladus. These photoelectrons are observed during Enceladus encounters in the energetic particle shadow where the spacecraft is largely shielded from penetrating radiation by the moon. We present a complex electron spectrum at Enceladus including evidence of two previously unidentified electron populations at 6–10 eV and 10–16 eV. We estimate that the proportion of “hot” (>15 eV) to “cold” (<15 eV) electrons during the Enceladus flybys is ≈ 0.1–0.5%. We have constructed a model of photoelectron production in the plume and compared it with ELS Enceladus flyby data by scaling and energy shifting according to spacecraft potential. We suggest that the complex structure of the electron spectrum observed can be explained entirely by photoelectron production in the plume ionosphere.

    Local Communities and Indigenous Peoples Platform: - potential governance arrangements under the Paris Agreement2018Book (Other academic)
    Abstract [en]

    Local communities and indigenous peoples (LCIPs) have been involved in the implementation of the UN Framework Convention on Climate Change (UNFCCC) since 1992. In 2015, the Paris Agreement introduced a new element to strengthen LCIPs efforts to address and respond to climate change – the LCIP Platform. This report develops potential options for making the LCIP Platform operational. A facilitative working group, an expert group or a dialogue platform could enable further exchange of knowledge, promote capacity building and enhance the engagement of local communities and indigenous peoples in the UNFCCC process. Proposals provided in this report were discussed at an informal meeting held in February 2018 in Helsinki, Finland. The international meeting was attended by representatives of experts and negotiators involved in the development of the LCIP Platform.

    Anpassning av HYPE-modellen för läckage-koefficienter och typhalter för att möjliggöra användandet av läckagekoefficienter och typhal-ter från jordbruk, hyggen, skog, myr, fjäll och öppen mark i HYPE-modellen Anpassning av HYPE-modellen för läckage-koefficienter och typhalter Anpassning av HYPE-modellen för läckage-koefficienter och typhalter Anpassning av HYPE-modellen för läckage-koefficienter och typhalter2013Report (Other academic)
    Abstract [sv]

    Projektets huvudsyfte är att sammanfoga HYPE-modellens (SMHI:s vattenkvalitets modell) beräkningar av vattenflöde samt kväve- och fosforprocesser med beräk-nade markläckagekoefficienter och typhalter. I projektet utreds även behovet av att tillföra en säsongsdynamik i läckaget av fosfor från åkermark.

    De typhalter för skog, myr, öppen mark, fjäll och hygge som använts vid PLC5-beräkningarna samt jordbruksläckage från NLeCCS har applicerats på alla delav-rinningsområden i S-HYPE 2010.

    De ursprungliga markprocesserna i HYPE-modellen är helt bortkopplade så att inget kväve- och fosforläckage beräknas. Istället beräknas markläckaget utifrån läckagekoefficienter och typhalter samt det vatten som lämnar varje markanvänd-ning. Markanvändningen i dessa beräkningar skiljer sig något från markanvänd-ningen i S-HYPE, därför viktas markläckaget mellan beräkningarna enligt en kopp-lingstabell. För de flesta markanvändningar finns en månadsvariation i form av en månadskoefficient som läggs till markläckaget från varje markanvändning för att skapa en årsdynamik.

    Efter att markläckaget, beräknat utifrån läckagekoefficienterna och typhalterna, implementerats sker inga förändringar av de processer som finns i originalversion-en av HYPE. Alltså vidtar de inbyggda sjö- och vattendragsprocesser som existerar sedan tidigare i modellen.

    Projektet, som enbart syftar till att sammanfoga HYPE-modellens beräkningar med beräknade markläckagekoefficienter från NLeCCS och övriga typhalter, innebär inte att modellen är färdig för beräkningarna till PLC6. En omfattande validering av modellen återstår för att utvärdera resultatets kvalitet och bedöma huruvida eventuella problem bör hanteras innan modellen kan tas i bruk för PLC6-arbetet. Dessutom behöver modellens atmosfärsdeposition och källfördelning ses över.

    Slutsatsen gällande säsongsdynamik i läckaget av fosfor från åkermark är att fos-forförluster, som orsakas av enstaka regntillfällen som skapar ytavrinning och makroporflöden, överskuggar eventuella tendenser till säsongsvariation av fosfors rörlighet och därmed även av fosforkoncentrationen i avrinnande vatten från åker-marken. Dynamiken av fosfor- och kväveförlusten bedöms vara mer flödesbero-ende än årstidsberoende.

    Water in and on ionic materials: Structure, energetics, and vibrations2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Many chemical and physical phenomena in nature, in industrial processes, and in our daily lives take place at water/solid interfaces. The aim of this thesis is to further our knowledge of such processes at a molecular level. Here theoretical calculations can provide new insights about molecular bonding, structure and dynamics and how these respond to the perturbations from the surroundings. Coalculations can also yield for example vibrational spectra to be directly compared with experimental ones and help in the interpretation. This thesis describes the results of quantum-mechanical and quantum-dynamical studies of water properties on ionic surfaces [NaCl(001), MgO(001) and CaO(001)] and in ionic hydrates [e.g Na2CO3∙10H2O, MgSO4∙11H2O, Al(NO3)3∙9H2O] with especial emphases on surface and interface systems. In particular, calculations of binding energies, OH stretching frequencies, in situ electric field, dipole moments and intra/intermolecular OH distances were performed and analyzed to probe the strength of the water–environment interplay and to disentangle the components of the perturbation. Furthermore, validation of a range of dispersion-inclusive DFT methods for binding energies of interface water and structure and vibrational properties of water in condensed systems also constitutes part of the thesis.

    Two correlations among the investigated properties were established and extensively explored: (i) OH stretching frequency vs. H-bond distance to characterize the H-bond strength and patterns on the surfaces and (ii) OH stretching frequency vs. local electric field to understand the effect of the water/hydroxide environment on the calculated gas-to-bound OH frequency shift behaviour. It was found that both the intact and dissociated water molecules on MgO(001) and CaO(001) follow essentially the same frequency-distance correlations. However, if the frequency is instead correlated against the in situ electric field from the environment, water and hydroxide ion follow different “frequency vs. field” curves. Both water and hydroxide curves, however, can be described by the same model, namely by an electrostatic dipole model presented in the thesis. The gas-to-surface frequency shifts can be traced back to the competition between the signs and magnitudes of the permanent and induced dipole derivatives along the stretching coordinate. Furthermore, the “frequency vs. field” model offers useful insights into the frequency shifts of various surface H-bond motifs on the H2O/MgO interface induced by the adsorption of multilayer cold water.

    Fighting Fakes - The Nordic Way2018Other (Other (popular science, discussion, etc.))
    Abstract [en]

    Word matters and is the foundation for dialogue and democracy and so is trust. Thus, the phenomenon “Fake News” understood as propaganda, lies, disinformation and fake factory stories are serious threats to our democracies.

    The Nordic Council of Ministers urges for finding ways to meet this challenge and is launching a booklet to create a debate on how to counter fakes and build trust in words and facts.

    The booklet is based upon results from a meeting in September 2017 of a high-level group of key experts on the topic and in particular from four experts contributing by focusing on media and information literacy, ethical standards and quality journalism to be among the best tools to counter fakes.

    This booklet will be launched at the UNESCO World Press Freedom Day 2018 in Accra asking for international feedback on its recommendations.

    Verksamhetsberättelse 2017: Centrum för kommunstrategiska studier CKS2018Report (Other academic)
    Abstract [sv]

    Under 2017 fyllde CKS 20 år, vilket firades med att den årliga kommundagen uppgraderades till en högtidlig jubileumsdag, som ägde rum den 16 november i Norrköping. Inför jubiléet gav CKS ut en antologi med namnet Att äga framtiden, i vilken en lång rad forskare, kommunföreträdare och debattörer medverkar. Förutom den upplaga som delades ut inför jubiléet, har boken efterfrågats från många håll.

    Vid sidan av antologin, där flera av CKS medarbetare medverkar, har forskarna vid CKS fortsatt att publicera sig i olika vetenskapliga sammanhang, med internationella tidskrifter och antologier, rapportserier och populärvetenskapliga sammanhang som exempel.

    År 2017 har också varit ett år då det blivit tydligt att CKS verksamhet expanderar. Ett nytt samarbetsavtal med Region Östergötland har trätt i kraft under 2017 som en viktig förstärkning av förutsättningarna för forskning om lokala och regionala frågor, samt kopplingarna däremellan. Nya forskningsmedel från externa finansiärer har landats av forskare på CKS, ofta i samarbete med forskare på andra avdelningar vid LiU eller på andra universitet. Sammantaget har dessa nya medel, tillsammans med grundfinansieringen från kommunerna och universitetet, skapat möjligheter att förstärka kompetensen inom CKS olika kunskapsfält genom rekryteringar av såväl forskare, som postdoktorer och forskningsassistenter. Via gästforskarprogrammet, egna konferenser och workshops har forskningsverksamheten ytterligare förstärkts.

    Inom CKS Lärande fortsatte under 2017 den viktiga utåtriktade verksamheten med en rad seminarier och lärandetillfällen för kunskapsutbyte mellan forskare, politiker, tjänstemän och en intresserad allmänhet. Ett nytt samarbete för kunskapsutbyte med kommunenheten vid Finansdepartementet har kommit till stånd under 2017, vilket är ett tecken på att CKS befäster sin position som en efterfrågad miljö för kommunrelevant forskning och forskningskommunikation.

    The report summarises the monitoring activities within the National Swedish Contaminant Programme for freshwater biota. Each monitored contaminant has been examined in pike, perch or Arctic char from 32 lakes from the north to the south in Sweden.

    No general trend could be seen for mercury, and all samples were above the EU target level. Lead was generally decreasing. Nickel showed a general upward trend in 50% of the perch lakes. An increase, or indication of an increase, was seen for chromium during the last ten years. Zinc concentrations were decreasing in a majority of the perch samples and in pike from Lake Storvindeln. Arsenic concentrations were increasing in Arctic char and pike from all sites and in perch from a third of the sampling sites. Tin concentrations decreased in the majority of the perch time series during the most recent ten years. No general trend was observed for copper, silver, aluminum, bismuth, and cadmium.

    In general, downward trends were seen for; PCBs, HCHs, DDT, DDE and PCDD/Fs in all species (with a few exceptions). The chlorinated compounds generally showed a somewhat higher concentration in the southern parts of Sweden. Most chlorinated compounds were below the suggested target levels.

    No general trend was seen during the monitoring period for PBDEs. Concentrations of PBDEs in Lake Bolmen increased from the 60s and peaked in 1992/1993 and have subsequently decreased. The concentration of HBCDD was under LOQ in a majority of the samples.

    Several of the perfluorinated carboxylic compounds showed an increase in concentration in arctic char, while PFOS and FOSA decreased. In perch PFOS has decreased since 1995. Higher concentrations of perfluorinated compounds can in general be seen in the southern part of Sweden. In all lakes, PFOS is below the target level for all species.

    Analysis of per- and polyfluoroalkyl substances (PFASs) in soil from Swedish background sites2018Report (Other academic)
    Abstract [en]

    Per- and polyfluoroalkyl substances (PFASs) are persistent organic pollutants with bio-accumulative and toxic potential. This study investigated the levels, composition profiles and geographical distribution of 28 PFASs in 31 soil samples from Swedish background areas. In total, 15 of the 28 analysed PFASs were detected, with an average concentration of 2.4 ng g-1 dw (median of 1.9 ng g-1 dw, n = 31). The dominant PFASs in the soil samples were perfluorooctane sulfonic acid (PFOS) (20 % of the Σ28PFASs), perfluorooctane sulfonamidoacetic acid (FOSAA, 15 %), 6:2 fluorotelomer sulfonic acid (6:2 FTSA, 14 %) and perfluorobutane sulfonic acid (PFBS, 13 %). Perfluorooctane sulfonic acid (PFOS) had also the highest detection frequency of the studied PFASs (77 %) in the soil samples with a median concentration of 0.30 ng g-1 dw. However, the guideline value for PFOS in soil for sensitive land use from the Swedish Geotechnical Institute (SGI) (3 ng g-1 dw) was not exceeded in any sample. However, assuming the same toxicity for all PFASs, the Σ28PFAS concentrations exceeded the guideline value (3 ng g-1 dw) in 9 out of 31 samples (29 %). PFOS and perfluoroundecanoic acid (PFUnDA) concentrations showed higher concentrations towards the south (significant negative correlation with latitude; p < 0.05), while FOSAA showed an opposite trend (p < 0.05). Furthermore, PFBS showed higher concentrations towards the west (significant negative correlation with longitude; p < 0.05). The proportion of PFOS (%) decreased significantly with latitude (i.e. towards the south), while the proportion of FOSAA (%) increased with latitude (p < 0.05). Furthermore, the concentrations of FOSAA, PFBS and perfluorotridecanoic acid (PFTriDA) showed a significant positive correlation with total organic carbon (TOC) (p < 0.05). The concentrations of FOSAA correlated significantly positive with both PFTriDA and PFBS (p < 0.05). Overall, PFASs were ubiquitously detected in Swedish background soil samples and showed distinguish geographical distribution. However, more data are needed regarding the pathways and sources of PFASs in soil and identifying potential hot spots.

    To double a recipe: interdisciplinary teaching and learning of mathematical content knowledge in a home economics setting2014In: Education Inquiry, ISSN 2000-4508, E-ISSN 2000-4508, Vol. 5, no 2, p. 301-318Article in journal (Refereed)
    Abstract [en]

    This study examines if interdisciplinary teaching can be said to facilitate the learning and use of fractions by Swedish 12-year-old pupils. Home and Consumer Studies is well suited to interdisciplinary teaching, and young people can therefore find it interesting to study maths since the setting is relevant to them. Building on variation theory and a learning study, we examined pupils' (n18) ability to double fractions greater than ½ when using a recipe. The general results show that what is to be learned benefits if it is presented in different ways, that teachers should not take pupils' knowledge for granted, and mathematically that it is not necessary to divide something to be able to double it. We argue that the study shows that genuine problems based on pupils' interest and life world can enhance motivation and, in turn, learning.

    Forms of uncertainty reduction: decision, valuation, and contest2018In: Theory and society, ISSN 0304-2421, E-ISSN 1573-7853, Vol. 47, no 2, p. 133-149Article in journal (Refereed)
    Abstract [en]

    Uncertainty is an intriguing aspect of social life. Uncertainty is epistemic,future-oriented, and implies that we can neither predict nor foresee what will happenwhen acting. In cases in which no institutionalized certainty about future states exists,or can be generated, judgment is needed. This article presents the forms by whichuncertainty is reduced as a result of judgments made about different alternatives in aprocess involving several actors. This type of uncertainty may exist, for example, aboutwhich artist is the best, which offer in the market is more valuable, which football teamis better than all the rest, or which research proposal will get a grant. The result ofdifferent forms of uncertainty reduction is increased certainty concerning alternatives inrelation to one another, such as good and bad, rank lists, scores, quality assessment, andBwinner and losers.^ Based on the result, uncertainty is reduced and action is facilitated.The forms are structural and comprise roles; may be legitimate in a smaller or largerdomain; and may exist in all spheres of life, as exemplified in sports competitions, inlabor markets, and in the ranking of universities. Three forms of uncertainty reductionbased on judgment are identified in this article: (1) decision, made by an authority; (2)valuation, by means of which order arises as a result of actors ascribing values; and (3)contest, by which an order is the result of direct struggle.

    Dynamic Rating of Power Lines and Transformers for Wind Energy Integration2018Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    Dynamic Rating (DR) is usually associated with unlocking the capacity of power lines and transformers using available information on weather conditions. Our studies show that Dynamic Rating is a broad concept that requires further study and development.

    The capacity of the majority of power devices is highly dependent on the heat transfer properties of the materials which the devices are made of. To ensure correct power limits of the equipment, one must take into consideration not only the power load, but also ambient conditions, such as: temperature, wind speed, wind direction, solar irradiation, humidity, pressure, radiation into the atmosphere and magnetic losses.

    Dynamic rating is created as an alternative to standard constant rating that is designed with reference to extreme weather and load conditions. Some areas are more likely than others to experience extreme weather conditions, which have a chance of occurring only a few days per year for short periods of time. Such a distribution of weather parameters gives an opportunity to embed existing material properties of the power equipment and achieve a better utilization of the grid.

    The following thesis is divided into two simultaneous topics: Dynamic line rating and Dynamic transformer rating. The division is motivated by the importance of analysing the operation of the above-mentioned parts of the power network in greater detail. Power lines and transformers play a significant part in grid planning and have a potential to result in economic benefits when used with DR.

    The main focus of the doctoral project "Dynamic rating of power lines and transformers for wind energy integration" is on exploring potential ways to connect power generated from wind to the grid with the help of dynamic rating technologies. Therefore, great focus of the work lies on the analysis of DR connection of variable energy sources such as wind farms.

    The thesis presents the comparison of different line rating methods and proposes a new way of their classification. Evaluation of dynamic line rating application has shown the possibility to expand the power grid with additional capacity from wind power generation. Literature analysis and detailed evaluation of the conductor heat balance models have led to experimental evaluation of the convective cooling effect.

    The dynamic transformer rating application has shown a possibility to decrease the size of the power transformer without shortcoming in component availability.

    Narrative mediation of the Occupy movement: A case study of Stockholm and Latvia2018In: Media and austerity: Comparative perspectives / [ed] Laura Basu ; Steve Schifferes ; Sophie Knowles, Abingdon: Routledge, 2018, p. 226-236Chapter in book (Other academic)
    Abstract [en]

    The economic crisis of 2007/2008 constitutes a moment of rupture not only for the financial markets, but also in terms of political engagement. In reaction to the crisis thousands took to the streets and squares in order to express their critique of the current political and economic system. The critical juncture also highlighted the role of media technologies for political organization and participation, which is reflected in comments on protests related to the financial crisis often over-emphasizing digital social media. This chapter provides an alternative way of engaging with crisis-related protest that moves beyond notions such as networked protests and connected action. Instead the chapter suggests reinvigorating more traditional methods of narrative analysis and critical hermeneutics in order to make sense of representations of protest mobilizations in reaction to the financial crisis. The financial crisis and protest that emerged in response serve as backdrop in order to further the theoretical argument about what role narrative mediation plays in the construction of social reality.

    Comparative microstructural and corrosion development of VCrNiCoFeCu equiatomic multicomponent alloy produced by induction melting and spark plasma sintering2018In: IOP Conference Series: Materials Science and Engineering, 2018, Vol. 329, no 1, article id 012016Conference paper (Refereed)
    Abstract [en]

    The present study focuses on the corrosion behavior of a single-phase FCC high entropy alloy (VCrNiCoFeCu) casted by two different methods: induction melting and spark plasma sintering. The corrosion resistance has been evaluated using immersion tests in 3.5% NaCl solution, the potentiodynamic polarization measurements and the results are compared how is dependent the corrosion rate as a function of the production methods. Our results show that induction melted sample is stable in salty environment. On the other hand, based on the changes of polarization curves, there must be an evolution of oxide films on the SPSed sample until reaching the stable oxide layer.

    Hospitalization due to stroke and myocardial infarction in self-employed individuals and small business owners compared with paid employees in Sweden—a 5-year studyIn: Small Business Economics, ISSN 0921-898X, E-ISSN 1573-0913Article in journal (Refereed)
    Abstract [en]

    Analysing Swedish population register data, the aim of the present study is to investigate differences in acute cardiovascular disease (CVD) in terms of stroke and myocardial infarction incidence between self-employed individuals and paid employees and to study whether the associations vary by gender or across industrial sectors. A cohort of nearly 4.8 million employed individuals (6.7% self-employed in 2003) is followed-up for hospitalization due to stroke and myocardial infarction (2004–2008). Self-employed individuals are defined as sole proprietors and limited liability company owners according to legal type of their enterprise. Negative binomial regression models are applied to compare hospitalization rates between the self-employed and paid employees, adjusted for socioeconomic and demographic confounders. Two- and three-way interaction are tested between occupational group, industrial sector, and gender. Limited liability company owners have significantly lower hospitalization for myocardial infarction than paid employees. Regarding two-way interaction, sole proprietors have higher myocardial infarction hospitalization in trade, transport and communication, and lower in agriculture, forestry, and fishing than paid employees. Limited liability company owners have lower hospitalization rate for myocardial infarction than employees in several industries. The results highlight the importance of enterprise legal type and industrial sector for CVD among self-employed individuals. © 2018 The Author(s)

    A cross-linguistic comparison of the event-structure of FETCH: Possible coding alternatives and their realizations2003In: Views & Voices – Inquiries into the English Language and Literature, Vol. 1, no 2, p. 69-92Article in journal (Refereed)
    Abstract [en]

    This paper presents the possible coding alternatives and the factual realizations of a complex event concept. We assume that any concept is built on a perceptional and functional basis and ask in what ways different languages encode such a concept, i.e., how the surface realizations of such a concept differ from one another. The concept under consideration in this paper, henceforth termed FETCH, is the concept realized in British English ‘fetch’ and Croatian ‘dohvatiti’. After characterizing the event structure of FETCH at the beginning, a discussion of potential coding alternatives in terms of conceptual vs. lexical chunking follows. We then compare the cross-linguistic encoding of FETCH in a sample of 29 languages and show how the different surface realizations demonstrate different instantiations of potential conceptual and lexical chunking. Moreover, we discuss whether the event concept FETCH itself is universal. Finally, we test current theories on event structures, with a focus on the often assumed binary construction scheme.

    Towards a connoisseurship in drama: Dimensioner av tyst kunskap i förhållande till kreativitet i en dramakontext2017Conference paper (Other academic)
    Abstract [sv]

    Vi hävdar att dramafältet behöver ett utökat vokabulär för att belysa och beskriva det ämnesspecifika kunnandet inom såväl praktik som forskning. Bristen på vokabulär försvårar såväl summativ bedömning som formativ konstruktiv feedback till våra deltagare. Vi söker efter vokabulär för att beskriva det ämnesspecifika inom drama. Dramaämnet innehåller flera hörnstenar såsom rolltagande, förflyttning i tid och rum och skapande. I detta paper kommer vårt fokus att ligga på det som vi anser är en grundläggande förmåga i ett dramaarbete; nämligen kreativitet. Konsten att tolka ett kreativt kaos är ett praktiskt tyst kunnande hos pedagoger som vi saknar vokabulär för.

    Utifrån Eisner begrepp Connoisseurship utforskar vi i detta paper hur vi kan tala om och synliggöra kvalitéer inom drama. Eisner definierar Connoisseurship som "konsten att uppskatta" vilket i sin tur ligger till grund för att ge konstruktiv kritik eller feedback inom ett specifikt ämnesområde. Connoisseurship är oftast en tyst kunskap som bygger på en gedigen ämneskunskap och erfarenhet. I detta paper vill vi försöka sätta ord på och synliggöra utvecklandet av ett Connoisseurship för drama.

    Eisner menar att konstruktiv kritik är en nyckel till att ge konstruktiv bedömning (2017;3) "Critisism is an art of saying useful things about complex and subtle objects and events so that others less sophisticated, or sophisticated in different ways, can see and understand what they did not see and understand before" (2017;3). Vi behöver lära oss att känna igen kvalitet som kan ligga till grund för en konstruktiv kritik vilket i sin tur kan fungera som konstruktiv bedömning.

    Frågan är dock om det går att hitta ett gemensamt språk för drama? Försvåras verbalisering i drama av att dramafältet är tvärvetenskapligt i den meningen att vi står på flera ben från t.ex. teater, pedagogik, socialt lärande, och psykologi? Hur kan ett Connoisseurship i drama i så fall se ut?

    Characterisation of time-dependent, statistical failure of cellulose fibre networks2018In: Cellulose (London), ISSN 0969-0239, E-ISSN 1572-882XArticle in journal (Refereed)
    Abstract [en]

    Cellulosic materials have special advantages for transport packaging, because of their light-weight and recyclable natures and also relatively high specific strength. The strength of such materials is normally evaluated by applying monotonically increasing, quasi-static displacement (or load). However, in real circumstances, the material is subjected to far more complex loading histories, such as creep, fatigue, and random loading. Failures under such circumstances are, not only time-dependent, but also notoriously variable. For example, the coefficient of variation for creep lifetime reaches or even exceeds 100%. The objective of this study is to develop a method to characterise both time-dependent and statistical natures of failures of cellulosic materials. We have used a general formulation of time-dependent, statistical failure, originally proposed by Coleman (J Appl Phys 29(6):968–983, 1958). We have identified three material parameters: (1) characteristic strength, representing short term strength, (2) brittleness parameter (or durability), and (3) Weibull shape parameter related to long-term reliability. These parameters were determined by special protocols of creep and constant loading-rate (CLR) tests for a series of containerboards. Results have shown that these two test methods yield comparable values for the materials parameters. This implies the possibility of replacing extremely time-consuming creep tests with the more time-efficient CLR tests. Comparing the cellulose fibre networks with fibres and composites used for advanced structural applications, we have found that they are very competitive in both reliability and durability aspects with Kevlar and glass-fibre composites.

    Why is emergy so difficult to explain to my ecology and environmental science friends?2018Report (Other academic)
    Abstract [en]

    Communication problems concerning the emergy concept, in an ecology/environmental science context are described. Problematic areas to communicate are identified, as 1) the different use of the energy concept, where adding up energies of different kinds are not accepted, 2) the size of tidal and deep heat emergy compared to solar energy, 3) the solar energy being represented by rainfall or land cycle, and 4) the view on value and connection to economics. Pedagogic experiences are shared regarding 1) how to communicate the energy hierarchy concept, 2) the communication benefits of decoupling the hypothesis' of energy hierarchy, maximum empower and pulsing, and 3) communication to economists regarding the emergy concepts relation to economics. Some larger contextual reasons influencing the communication are also identified as 1) the important paradigm shift in ecology during the 1970s, from a holistic ecosystem ecology to a reductionistic population and community ecology, and 2) the dualistic view of quantity and quality regarding the four main types of flows existing in systems (energy, mass, money and information), where useful qualitative measures seem to be missing as a complement to the quantitative measure of information in bits. The main recommendation from this paper is that even more carefulness is spent on explaining that the emergy concept relies on the theory of the energy hierarchy, with the implication that the energy concept is used in a slightly, but very important, different way than by most scientists.

    Collaborative workplaces for innovation in service companies: barriers and enablers for supporting new ways of working2018In: Service Business: An International Journal, ISSN 1862-8516, E-ISSN 1862-8508Article in journal (Refereed)
    Abstract [en]

    The paper aims to provide a systematic overview of the barriers and enablers that contribute to the success or failure of collaborative workplaces initiatives aimed at fostering innovation in service companies. The study is based on semi-structured interviews with innovation managers, human resource managers and facility department executives from a sample of multi-national service companies. Its primary focus is on the workplace initiatives carried out in their Spanish subsidiaries. The paper contributes to the extant research by identifying a conceptual model for collaborative workplaces and by providing a systematic overview ofthe related barriers and enablers. From the interviews, these factors were organized within a framework usable by practitioners for analysis. This paper is of interest to companies that aim to design collaborative workplace strategies to justify associated investments. It can also provide their managers with guidelines to lead the company in the transition toward new ways of working based on higher employee collaborationand flexibility.

    Opportunities and challenges of mobile payment services: The perspective of service providers2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

     Mobile payments are transforming the payments industry. These services open up the opportunity for non-banking actors to enter the market. In order to embrace this challenge, banks, traditional payments market players, are forced to launch mobile payments. However, in Europe and most developed economies, a big number of launched services get terminated soon after their introduction in the market. Hence, the ability of different actors to act locally calls for additional research.

    The main objective of this thesis is to broaden knowledge and understanding about the ways mobile payment service providers address the opportunities and challenges of mobile payment services. In order to investigate this problem, this research (i) explores factors stimulating and hindering the introduction of mobile payments using perspectives of different types of service providers (i.e., banks, independent providers, direct operator billing providers, retailers, and public transport companies) and (ii) seeks to explain the importance of these factors for each type of provider.

    The primary data collected using interview method. More than 40 industry representatives in six countries were contacted. The Service, Technology, Organisation, and Finance (STOF) model was used as a theoretical research framework. This is a business modelling framework that specifies a set of critical design issues that have to  be considered within each model’s domain.

    Research findings highlight that the organisation domain is the key domain, which  affects all other domains and has an impact on the general viability of the business model. A comparison of the approaches used by different service providers to address each of the critical design issues helped to identify the factors that are most important within each domain. These factors stimulate or hinder development of a viable business model within each category of service providers.

    This research contributes to a better understanding of challenges and success factors associated with the design of business models for new mobile services and uses the lens of the STOF model. The contributions to the academic research on mobile payments are: (i) collection and analysis of a rich empirical data set on mobile payment services implemented in six Northern European countries, (ii) discussion of a bigger picture by connecting research findings to the context of the existing payment system, (iii) extension  of knowledge on business models for mobile ticketing, and (iv) extension of knowledge on the value of mobile ticketing services in the business-to-business (B2B) context.

    Designing for Adaptable Learning2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    The research in this thesis emphasizes the endeavor of designing for adaptable learning. Designing for adaptable learning is understood as an overall response to designing for integration work. Designing for integration work is thus classified as a special case of designing for adaptable learning. Integration work in this research is understood as a professional practice that aims to improve and support the integration process of newly arrived immigrants (referred to as newcomers) in society. As professional practitioners of integration work, integration workers face daily challenges that are wicked by nature. In order to understand and problematize these challenges, the empirical work of this research was organized and performed within a case of digitalizing the civic orientation program in Sweden. The civic orientation program is a special case of integration work in Sweden, where integration workers organize and provide civic orientation to newcomers in Sweden. Different groups of newcomers are subsequently participating in a required 60 hours of civic orientation and are provided sessions through their native language. The integration workers are responsible for organizing and performing civic orientation through a dynamic process of dialogues, exercises, and more. Integration work as a practice, however, does not incorporate a standardized knowledge base, which provides integration workers a unified way of organizing and performing civic orientation. Instead, different counties and municipalities in Sweden organize and perform civic orientation in various ways. Furthermore, due to the extreme heterogeneity among newcomers as participants in civic orientation, the integration workers are forced to adapt. In turn, the integration workers themselves are heterogeneous due to their different roles, areas of responsibilities, and more essentially, worldviews. In order to understand and problematize the aspects of designing for integration work, an explorative approach was adopted through three consecutive cycles of Action Design Research. The cycles were performed from 2013 until completion of this thesis. The thesis was subsequently governed through three research questions: (1) How to design for integration work? (2)What makes designing for integration work significant? (3) Why do design for integration work? There search questions were addressed and answered through a body of produced knowledge that captures and provides the essential contributions of the thesis. The contributions of the thesis highlight different aspects of designing for integration work, as a special case of designing for adaptable learning. Thus, the contributions are presented and discussed with an explicit bearing toward designing for adaptable learning,as the general class of problems and solutions of this research. The contributions are consequently provided through: (1) an ensemble artifact that is termed a digital platform for civic orientation; (2) an Information Systems Design Theory for adaptable e-learning; (3) a design research methodology that incorporates work-integrated learning; (4) the meta-design of an open learning platform that supports the social integration of newcomers in society; and (5) a philosophical concept that problematizes and conceptualizes the essence of presence in e-learning. Ultimately, the research contributes to the research domains of information systems and work-integrated learning, by providing findings that problematize core aspects of designing for adaptable learning. Furthermore, the thesis extensively discusses the findings of this research by emphasizing a philosophical perspective toward core aspects of the research contributions. Finally, the thesis concludes with a set of limitations of the current research and a brief discussion about potential endeavours of future research.

    Expectations and the performance of governance functions between a board, management and other stakeholders: the case of Robotdalen2018In: Journal of Management and Governance, ISSN 1385-3457, E-ISSN 1572-963X, p. 1-23Article in journal (Refereed)
    Abstract [en]

    Previous research has called for an enhanced understanding of the dynamic and interactional aspects of board work in public sector governance. Using a longitudinal case study of Robotdalen, this paper attempts to meet this call through a processual and qualitative study of board work in public organisations. The aim of the paper is to enhance our understanding of the human side of governance and the interactions between a board, the management in the governed organisation and other stakeholders. We do this by addressing the theoretical concept of an expec- tations gap. The results demonstrated how funding regimes in uence governance functions, structures and practices at the organisational level, and how internal actors such as managers also carry out governance functions. Moreover, the results show how an expectations gap shifts and changes over time. In this way we have contributed a more nuanced theoretical understanding of how the governance func- tion is co-produced and the importance of understanding the expectations gap to further understand the dynamics of public sector board work.

    Abstract [en]

    Background: The level of complexity within healthcare services is continually increasing. These services are put under pressure by changing demographics and associated illness profiles, the influence of globalization, and the introduction of new technologies. Physicians are expected to perform and develop their daily work in cooperation with other healthcare professionals and in association with increasing levels of patient involvement. In such a changing and challenging healthcare environment, more knowledge is needed about how learning takes place and how learning can be facilitated and developed in the daily provision of healthcare services.

    Aim: The overarching aim of this dissertation is to deepen our knowledge and understanding of the pedagogic processes and the learning that takes place in healthcare practices, with particular focus on physicians’ learning.

    Methods: The research methodology employed in this dissertation includes interviews and field studies that used an interactive research approach. Authentic healthcare practices, including physicians, other care providers, patients, clinical tools in use, and the spatial arrangements within which the healthcare practices were performed were studied. The data that was collected was analyzed from a practice-theory perspective, thus allowing the researcher to identify and describe several dimensions of learning and interaction in healthcare practices.

    Results: The pedagogic processes that were identified in the physicians’ and the other healthcare practitioners’ daily work with their patients can be described as read-guide-learning support. The pedagogic dimension of this work was not immediately revealed nor was it overtly articulated. The physicians dynamically, by themselves, taught and supported the junior physicians and other healthcare providers’ learning. The physicians’ mobility in a variety of healthcare contexts was of relevance to the learning that took place. By viewing specific healthcare contexts as performing health care practices during the study, a rounds work emerged which included both (i) co-produced learning rounds and (ii) operative rounds which gave rise to limited learning. The interaction between arrangements in healthcare practices, ‘practice architectures’, and the performance of the healthcare practices actually limited the junior physicians’ learning.

    Implications of the study: A proper understanding of the learning that takes place during the daily work in the provision of healthcare – by revealing and examining the pedagogic dimensions of the work that is done – can contribute to the development of learning and learning support mechanisms. Co-produced learning healthcare practices, where each participant’s needs and contributions are taken into account, have direct implications for professional development initiatives and learning, for patient involvement in their healthcare arrangements, and for interprofessional and inter-disciplinary cooperation. Such practices also provide responsible leaders and decision-makers with the opportunity to tie in healthcare quality assurance work with the daily work that is performed by healthcare practitioners in the field.

    Pedagogiskt ambassadörsprojekt "Mer skärmtid för lärarna"2018Conference paper (Other (popular science, discussion, etc.))
    Abstract [sv]

    Syfte. Det pedagogiska ambassadörsprojektet ”Mer skärmtid för Romklass lärare” syftade till att främja vidareutvecklingen av lärarnas digitala kompetens vid Romanska och klassiska institutionen. Närmare sagt var syftet att hjälpa lärarna vid Romklass att utveckla den digitala kompetensens olika dimensioner: (1) den didaktiska digitala kompetensen (som gör det möjligt att bedöma när digitala lärresurser kan eller bör användas); (2) den tekniska digitala kompetensen (lärarnas "IT-vana"); (3) den teoretiska digitala kompetensen (det vill säga kunskapen om forskningen om IT och lärande).

    Vad som genomförts. Inom ramen för detta projekt har det anordnats en lunchseminarieserie om användning av digitala lärresurser vid institutionen. För att kunna utveckla den digitala kompetensens olika dimensioner har seminarierna varit både praktiska och teoretiska. En metodportal som presenterar olika undervisningsmetoder baserade på användningen av IKT (med särskilt fokus på omvänt klassrum) är under uppbyggnad.

    Resultat. Seminarieserien har bidragit till att sprida kunskaper om och väcka diskussioner kring användningen av IT-baserade pedagogiska metoder. Användningen av digitala lärresurser har blivit ett ämne som har tagits upp i olika fora vid Romanska och klassiska institutionen, såsom lärarmöten och institutionskonferenser. Ett antal lärare är nu engagerade i olika pedagogiska utvecklingsprojekt med ett IKT-inslag.

    Några lärdomar och råd. Tidigare hade Romanska och klassiska institutionen inga institutionaliserade pedagogiska seminarier för sina samtliga lärare. Detta projekt har visat att det finns ett intresse för att diskutera pedagogiska frågor. Lunchseminarier har varit ett bra forum för detta, då de har möjliggjort att med jämna mellanrum samla lärare trots deras fullspäckade schema.

    Att väcka lust och intresse för fonetik med omvänt klassrum2018Conference paper (Other (popular science, discussion, etc.))
    Abstract [sv]

    Fonetik är en delkurs i allmän och fransk fonetik som ingår i kursen Franska I vid Romanska och klassiska institutionen (Stockholms universitet). I många år hade denna delkurs getts i föreläsningsform. 2015 började jag genomföra den med omvänt klassrum (’flipped classroom’). Syftet var att väcka lust och intresse för fonetik hos fler studenter.

    Omvänt klassrum innebär att studenterna börjar med att titta på videoinspelade föreläsningar hemifrån. På delkursen Fonetik har studenterna tillgång till videomaterialet på lärplattformen Scalable Learning. Denna plattform gör det möjligt att lägga in frågor (t.ex. flervalsfrågor) i videorna så att studenterna kan testa sina kunskaper medan de tittar på videorna. De måste besvara dessa frågor för att få titta vidare på filmerna. Studenternas svar syntetiseras automatiskt i en lättöverskådlig översikt som hjälper läraren att identifiera aspekter som hen behöver återkomma till under lektionen. Lektionstiden ägnas åt kunskapsfördjupande aktiviteter såsom diskussioner och tillämpningsövningar.

    Analysen av 235 kursutvärderingar från perioden HT2013–VT2017 visar att det nya kursupplägget har mottagits väl av studenterna. Efter implementeringen av omvänt klassrum ökade den genomsnittliga andelen studenter som tycker att kursen har varit stimulerande och intresseväckande i hög eller ganska hög grad från 73 % till 89 %, vilket motsvarar en ökning på 22 % (16 procentenheter). Andelen studenter som tycker att lektionerna har haft utrymme för givande studentaktivitet i hög eller ganska hög grad ökade med 35 %.

    Implementeringen av omvänt klassrum på delkursen Fonetik har alltså haft en positiv effekt på studenternas intresse för ämnet. Detta beror förmodligen till stor del på att lärandet blivit mer effektivt och stimulerande. Efter denna positiva erfarenhet har jag börjat använda omvänt klassrum i mina andra kurser.

    School Choice in Ethnically and Socioeconomically Heterogeneous Residential Areas

    This article explores how young peoples' strategies when choosing upper secondary education are marked by the segregation and marketization of education. Research is limited to five municipalities in southern Stockholm that are characterized by ethnically and socioeconomically heterogeneous residential areas. It is argued that the school choice of all pupils at upper secondary level in this region constitutes a socio-geographical space in which the school market is embedded and operates. This space is explored by means of specific multiple correspondence analyses (specific MCA). Using individual census data on all students in the designated municipalities from 2008, the differences between 4 421 pupils are investigated as regards their parents' education, income, occupation, services, and national origin, as well as the pupils' academic merits from comprehensive school. The analysis reveals that, despite a "free" school choice and substantial geographical mobility, pupils' choices are heavily restricted by local social and demographic conditions, not the least those connected to their acquired and inherited assets.

    Dignity in the Workplace. The Perspective of Humanistic Management2018In: Journal of Management and Business Administration. Central Europe, ISSN 2450-7814, E-ISSN 2450-8829, Vol. 26, no 1, p. 171-188Article in journal (Refereed)
    Abstract [en]

    Purpose: The aim of this article is to fll the gap in the Polish discourse on management about the concept of dignity in the workplace. The text presents the issue from the perspective of humanistic management. The article analyzes contemporary discussion about dignity in the workplace conducted in the Western discourse on management.

    Methodology: The reflections stem from a critical analysis of popular concepts of dignity in the workplace in the management discourse. The author also uses the existing results of empirical research. The analysis uses management literature on dignity, which is the basis for systematizing available concepts.

    Findings: The literature analysis enables systematization of various concepts of dignity in the workplace and identifcation of specifc levels in the quality of employee treatment in an organization. Hence, the author identifes a few key factors that affect employees’ dignity in the workplace both positively and negatively and indicates mechanisms that allow for the humanization of work processes.

    Research limitations: The theoretical reflections should be verifed by empirical research in organizations. However, the area of research on dignity in the workplace is not problematized enough, potential problems still require in-depth theoretical research.

    Practical implications: The reflection on dignity in the workplace emphasizes the organizational mechanisms that lead to the humanization and dehumanization of work processes. The problematization of the category of dignity should allow researchers to conduct empirical research in organizations and managers to design organizational solutions that protect the well-being of their employees which, in consequence, may have a positive impact on the organization’s development.

    Originality: The article discusses the concepts of dignity in the workplace which are absent in the Polish discourse of management and indicates directions of further research in the feld.

    Professionalism, governance and inclusive education – A total population study of Swedish special needs educators2018In: International Journal of Inclusive Education, ISSN 1360-3116, E-ISSN 1464-5173, p. 1-16Article in journal (Refereed)
    Abstract [en]

    Prior research shows that special needs educators (SNEs) have had problems defining their occupational roles and jurisdiction, particularly regarding inclusive education. There are two occupational groups of SNEs in Sweden, namely special educational needs coordinators (SENCOs) and special education teachers. In this paper, we use the collective name SNEs to refer to both groups. Here, results from a total population study of Swedish SNEs are presented (N?=?3367, response rate 75%). The aim is to explore differences in SNEs? interpretation of school difficulties and if these differences are influenced by SNEs? employment in different parts of the school organisation. Statistical cluster-analysis was used to categorise SNEs into five distinct groups based on how they view the problems of pupils in school difficulties. Key concepts employed in the analysis are, primarily organisational vs occupational governance in relation to professional jurisdiction. Findings suggest that SNEs are less unanimous in their views of school problems, than prior research indicates. The variance is partly due to where they work in the school organisation, but we also find indications that different groups of SNEs experience different forms of governance with regard to their professionalism. The results are important due to the scope of the data and method of analysis as well as the illustrated variance of professional values and situations of SNEs and the potential consequences for the development of inclusive education.

    The role of implementation science in healthcare improvement efforts: investigating three complex interventions2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    For decades, scholars have found significant gaps between the knowledge available and the knowledge applied in healthcare. Many potential benefits of adequate knowledge based interventions are therefore never achieved. A considerable body of knowledge has evolved on how to promote a better uptake of evidence-based knowledge into routine use. Even so, the actual impact and usefulness of implementation research findings among healthcare practitioners have not been extensively studied.

    Accordingly, the overall aim of this thesis is to contribute to the understanding of how the implementation of complex interventions into healthcare can be improved. This is done by investigating whether some of these efforts do correspond with available scientific knowledge on implementation.

    The thesis is based on three cases contributing to four studies. The cases studied are: the National Perinatal Patient Safety program (NPPS), the Dynamic and Viable Organisation initiative (DVO), and the International Child Development Program (ICDP). All studies focuses on the early stages of implementation.

    A mixed methods approach was adopted, involving both qualitative and quantitative methods. Data collection consisted of interviews, questionnaires, observations, and process diaries. Qualitative content analysis (conventional and directed), descriptive and non-parametric statistics were used. The focus was on implementation strategies used by healthcare actors in relation to factors influencing implementation processes and outcomes. More specifically, healthcare actors perspectives on such factors and whether they were addressed by the strategies used, was investigated. A process evaluation of implementation outcomes was also part of the thesis.

    The healthcare actors in focus were the adopters, i.e. practitioners expected to change their work practices, and implementation facilitators. The latter refer to actors with a more or less explicit responsibility to implement new practices or interventions aimed at improving the quality and effectiveness of the provided health services.

    Variation was found regarding how the implementation strategies used in the three cases corresponded with available scientific knowledge on implementation. In Case NPPS, the implementation facilitators planned, designed, and ensured that the core interventions of the implementation strategy were executed in a rational manner. Several important implementation factors were addressed by the strategy. The process evaluation of effects on readiness for change by the development of a team mental model among adopters showed positive results.

    In Case DVO a strategy was used that evolved over time, partly based on raised questions and feedback from staff and managers involved. The strategy can be described as an intuitive ‘socially accomplished activity’. This strategy involved addressing ‘Implementation Process-related factors’ in order to affect motivation and increase the tension for change among adopters.

    In Case ICDP, the results reflected a shortage of strategies during the early stage of implementation. The main intervention was the stepwise ICDP-education. A more comprehensive implementation strategy covering implementation factors highlighted as important among adopters was not developed. The process evaluation revealed vague directives on what was expected regarding the use and adaptation of ICDP to current practice versus preservation of fidelity to the original ICDP. This situation resulted in a rather large variation in how the changes in work practices were perceived among the health centres involved. No health centre practiced ICDP in its original form.

    A new knowledge-practice gap is discussed based on the findings in this thesis: a gap between the scientific knowledge on implementation and the actual implementation strategies used in practice during improvement efforts initiated by healthcare actors. The findings show that correspondence between scientific knowledge on implementation and what is actually done in order to accomplish change in practice might be more random (or implicit) than systematic. The question of how to transfer scientific knowledge on implementation into user-friendly resources for practitioners is discussed. A tentative model is suggested, which contributes to existing determinant frameworks by focusing on relations among factors. The model may be used in healthcare practice, to guide the design of an implementation strategy (or as a pathway for tailored implementation interventions) and aid the assignment of responsibilities in relation to factors that are known to affect implementation processes and outcomes.

    The question of how to transfer models and frameworks into user-friendly resources needs further attention. It is suggested that action oriented research aiming at further developing and establishing the concept of ‘practical implementation science’ should be conducted. This could be a way of bridging the knowledge-practice gap in healthcare.

    Cooperative Manipulation and Identification of a 2-DOF Articulated Object by a Dual-Arm Robot2018In: / [ed] IEEE, 2018Conference paper (Refereed)
    Abstract [en]

    In this work, we address the dual-arm manipula-tion of a two degrees-of-freedom articulated object that consistsof two rigid links. This can include a linkage constrainedalong two motion directions, or two objects in contact, wherethe contact imposes motion constraints. We formulate theproblem as a cooperative task, which allows the employment ofcoordinated task space frameworks, thus enabling redundancyexploitation by adjusting how the task is shared by the robotarms. In addition, we propose a method that can estimate thejoint location and the direction of the degrees-of-freedom, basedon the contact forces and the motion constraints imposed bythe object. Experimental results demonstrate the performanceof the system in its ability to estimate the two degrees of freedomindependently or simultaneously.

    The Gatekeeper of the ICC: Prosecutorial Strategies for Selecting Situations and Cases at the International Criminal Court2017In: Georgetown Journal of International Law, Vol. 48, no 5Article in journal (Other academic)
    Abstract [en]

    The Office of the Prosecutor (OTP) of the International Criminal Court (ICC) has a unique role in the proceedings before the Court. It is the organ primarily tasked with choosing among the numerous situations and cases under the Court’s jurisdiction. The legal criteria for situation and case selection, provided in the Rome Statute and related regulations, are relatively open as to allow the Prosecutor a considerable degree of discretion. In order to guide this discretion, the Office of the Prosecutor has developed certain policies and strategies. Prosecutorial policy and strategy stands, almost by definition, at a crossroads between law and politics. This Article identifies strategic choices of the OTP in situation and case selection and analyzes them in relation to the ICC’s objectives. There are tensions between the need for predictability and legal certainty on the one hand and for pragmatism and case-by-case flexibility on the other hand. The Article finds that the OTP is downplaying its own discretion by emphasizing the legalistic and apolitical character of its decision-making and bringing the objectives of ending impunity, preventing crimes, and providing redress to victims to the fore. The objectives of restoring peace and security and of contributing to a historical record have been secondary to the OTP’s strategic choices.

    Matrix-Less Methods for Computing Eigenvalues of Large Structured Matrices2018Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    When modeling natural phenomena with linear partial differential equations, the discretized system of equations is in general represented by a matrix. To solve or analyze these systems, we are often interested in the spectral behavior of these matrices. Whenever the matrices of interest are Toeplitz, or Toeplitz-like, we can use the theory of Generalized Locally Toeplitz (GLT) sequences to study the spectrum (eigenvalues). A central concept in the theory of GLT sequences is the so-called symbol, that is, a function associated with a sequence of matrices of increasing size. When sampling the symbol and when the related matrix sequence is Hermitian (or quasi-Hermitian), we obtain an approximation of the spectrum of a matrix of a fixed size and we can therefore see its general behavior. However, the so-computed approximations of the eigenvalues are often affected by errors having magnitude of the reciprocal of the matrix size.

    In this thesis we develop novel methods, which we call "matrix-less" since they neither store the matrices of interest nor depend on matrix-vector products, to estimate these errors. Moreover, we exploit the structures of the considered matrices to efficiently and accurately compute the spectrum.

    We begin by considering the errors of the approximate eigenvalues computed by sampling the symbol on a uniform grid, and we conjecture the existence of an asymptotic expansion for these errors. We devise an algorithm to approximate the expansion by using a small number of moderately sized matrices, and we show through numerical experiments the effectiveness of the algorithm. We also show that the same algorithm works for preconditioned matrices, a result which is important in practical applications. Then, we explain how to use the approximated expansion on the whole spectrum for large matrices, whereas in earlier works its applicability was restricted only to certain matrix sizes and to a subset of the spectrum. Next, we demonstrate how to use the so-developed techniques to investigate, solve, and improve the accuracy in the eigenvalue computations for various differential problems discretized by the isogeometric analysis (IgA) method. Lastly, we discuss a class of non-monotone symbols for which we construct the sampling grid yielding exact eigenvalues and eigenvectors.

    To summarize, we show, both theoretically and numerically, the applicability of the presented matrix-less methods for a wide variety of problems.

    SDN-Enabled Resiliency in Computer Networks2018Licentiate thesis, comprehensive summary (Other academic)
    Abstract [en]

    In computer networking, failures, such as breaking equipment, cable cuts, power failures and human errors continuously cause communication interruptions. Such failures may result in dissatisfied customers, loss of product reputation, violation of SLAs and even critical failures in industrial systems. SDN, which logically centralizes the control plane, is an emerging technology in computer networking. The global view provided by the SDN controller can be used to reconfigure the network in case of a link failure. However, this reconfiguration may take too long for high availability networks. With the introduction of proactive link repair, backup paths are preinstalled in the forwarding devices, reducing path recovery time.

    This thesis addresses the usage of SDN to provide resiliency in high availability networks. First, we consider how SDN can be used for increasing the reliability of ICNs. Second, we investigate how similar technologies could be applied to deal with fast channel attenuation and resulting outage in mmWave backhaul networks. Finally, we look at CloudMAC-based Wireless LAN, and how SDN-enabled QoS improvements could improve connection reliability.

    What Can We Say Regarding Shared Parenting Arrangements for Swedish Children?2018In: Journal of Divorce and Remarriage, ISSN 1050-2556, E-ISSN 1540-4811Article in journal (Refereed)
    Abstract [en]

    Joint physical custody (JPC) refers to children living alternatively and about equally with both parents after a parental separation or divorce. The practice has been debated in relation to child well-being because of the frequent moves imposed on children and the potential stress from living in 2 homes. This study describes the background to the high frequency of Swedish children in JPC and the results from research on Swedish children’s well-being in this living arrangement. Children in JPC report better well-being and mental health than children who live mostly or only with 1 parent. No Swedish studies have found children’s health to be worse in JPC than in sole parental care from child age of 3 years and beyond. The existing literature cannot, however, inform us about the mechanisms behind the findings. The risks of selection effects into living arrangements are plausible. For this purpose, longitudinal studies are warranted.
